Suppose that the probability that a person will develop hypertension over a life time is 60%. Of 13 graduating students from the

Savatey [412]

Answer:

The mean number of the students who develop hypertension over a life time is 7.8.

Step-by-step explanation:

For each person, there are only two possible outcomes, either they will develop hypertension, or they will not. The probability of a person developing hypertension is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

Suppose that the probability that a person will develop hypertension over a life time is 60%.

This means that $p = 0.6$

13 graduating students from the same college are selected at random.

This means that $n = 13$

Find the mean number of the students who develop hypertension over a life time

$E(X) = np = 13*0.6 = 7.8$

The mean number of the students who develop hypertension over a life time is 7.8.

*please help* If multiple forces are acting on an object, which statement is always true?

Montano1993 [528]

Answer: You are correct. The answer is choice C.

The sum of the vectors is the resultant vector, which is where the net force is directed.

An example would be if you had a ball rolling on a table and you bumped the ball perpendicular to its initial velocity, then the ball would move at a diagonal angle rather than move straight in the direction where you bumped it.

Acceleration is the change in velocity over time, so the acceleration vector tells us how the velocity's direction is changing.
